5 Claims.

This invention relates to improvements in valves and, more especially, awater valve adapted for use in controlling the supply to a Water closettank, such valves being commonly known as ball cocks.

Among the features of my invention is the provision of such a valveadapted to be pontrolled by a float, which will close relatively rapidlyas the water reaches the required height. By this construction, the tankis .filled rapidly after fiushr ing and again ready for use.

Anotherfeature of my invention is the prevision of valve mechanism thatis efficient and rapid in operation and so made that the direction ofoperation of the valve can be easily reversed. My improved valvemechanism is also removable as a unit to permit inspection, repair andreplacement.

Other features and advantages of my invention will appear more fully asI proceed with my specification.

In that form of device embodying the features 'of my invention shown inthe accompany ng drawing Figure 1 is a vertical sectional view takenthrough a tank showing my improved valve installed therein; Fig. 2 is avertical sectional view of the valve; Fig. 3 is a view similar to Fig. 2

showing the valve closed; Fig. 4 is a similar View showing the valveopen; and Fig. 5 isa view in perspective and partly in section of thesleeve and :valve stem.

As shown in the drawing, indicates a tank, for example, a water closetsupply or flush tank; 11, the water therein; 12, the ball cockcontrolled by the float 13; 14, the usual overflow; 15, the refill pipe;and 16, the outlet or flush pipe con- .trolled by the rubber ball 17.

My invention relates to the construction of the valve 12 and the samewill now be described in detail. Numeral 18 indicates a substantiallyspherical casing with the inlet opening 19 and outlet 20 leading to theinlet and outlet chambers '19 and 20 respectively, separated by thepartition or diaphragm 21 with the opening 22 therein. At one side,opposite the hole 22, the casing 18 is provided with an exteriorlythreaded cylindrical extension 18 adapted to receive the valve mechanismto be hereinafter described.

The valve mechanism includes a cylindrical sleeve 23 with a removablevalve seat 24 at the inner end. 25, 25 indicate holes for the passage ofWater, as indicated by the arrows.

Numeral 26 indicates a cap adapted to be screwed onto the extension 18to cover the same and hold the sleeve and cap therefor in place. 27

Longitudinal movement of the stem 27 outwardly causes the valve disc 28to rest on the seat 24 to close the valve and longitudinal movement inthe opposite direction opens the valve. Co.-operating cam surfaces areprovided on the sleeve 23 and the stem 27.whereby rotation of the ,stemin one direction will close the valve. There is also provided a camsurface on the cap oo-operating with a cam surface on the stem wherebyrotation of the stem in the reverse direction will open the valve. Thereis also provided a cap 31 for the sleeve 23. Rotational adjustment ofthis cap grill reverse the valve action, as will be deseribed. As hereshown, the cam surfaces on the stern and sieeve'ne so arranged thatrotation of the stern in either direction with the cap removed willclose the'valvi. The cam surface on the gap when the same is in placecooperates with a cam surface on the stem to prevent closing of theValve by rotation of the stem in one direction. The desired direction ofrotation may be obtained by adjusting the p0;- sition of the cap. Thecam' surfaces on the sleeve 23, stem 27 and cap 31 above referred to aredouble. That is, each carries twosuch cam surfaces diametricallyarranged. It Will be necessary to describe but one in order to show theaction in the valve. The cam surfaces on the sleeve 23 are indicated by32. These comprise two V-shaped members. The stem 27 carries acylindrical enlargement 33 provided with V-shaped notches defined by thecam surfaces 34. The V-shaped members formed by the surfaces 32 areindicated by 32 The cap 31 is provided with cam surfaces on V- shapedmembers similar to the cam surfaces 32 on the sleeve. And the member 33on the stem carries v shaped notches with the cam surfaces 36 adapted toco-operate with the cam surfaces 35 on the cap. With the cap removed, itwill be seen that the surfaces 34 on the stem will ride on the surface32 on the sleeve so that rotation of the stem in either direction willclose the valve. The cap may be adjusted, however, so that the camsurfaces 35 will engage the surfaces 36 so that rotation of the sleevein one direction will operate to open the valve. When so adjusted, thecam surfaces 35 on the cap will also co-operate with the cam surfaces 36on the stem to permit rotation of the stem in one direction to close thevalve and prevent rotation of the stem in the opposite direction toclose the valve.

One of the V-shaped members 37 on the cap is provided with a pin 38adapted to be engaged in either one of the two slots 39 or 39 n the edgeof the sleeve 23. When the pin 38 is in the slot 39, as shown in thedrawing, rotation of the stem 27 in a clockwise direction to close thevalve is permitted; whereas rotation of the stem in a counterclockwisedirection to close the valve is prevented. When in this position,rotation of the stem in a counterclockwise direction operates to openthe valve. When the pin 38 is placed in the slot 39 the action of thevalve is reversed. That is, counterclockwise rotation of the stem willclose the valve and clockwise rotation will open it.

While I have shown and described certain embodiments of my invention, itis to be understood that it is capable of many modifications. Changes,therefore, in the construction and arrangement may be made withoutdeparting from the spirit and scope of the invention as disclosed in theappended claims, in which it is my intention to claim all noveltyinherent in my invention as broadly as permissible, in View of the priorart.

What I regard as new, and desire to secure by Letters Patent, is:

1. Valve mechanism of the character described, including; a sleeve witha valve seat at one end; a cap for the sleeve at the other end; a valvestem rotatably mounted in the sleeve and extending through the cap; avalve disc on the stem co-operating with the seat by longitudinalmovement of the stem to open or close the valve; co-operating camsurfaces on the sleeve and stem whereby rotation of the stem in onedirection will close the valve; a cam surface on the cap co-operatingwith a cam surface on the stem, whereby rotation of the stem in thereverse direction will open the valve; and means by which rotationaladjustment of the cap will reverse the valve action.

2. Valve mechanism of the character described, including; a sleeve witha valve seat at one end; a cap for the sleeve at the other end; a valvestem rotatably mounted in the sleeve and extending through the cap; avalve disc on the stem co-operating with the seat by longitudinalmovement of the stem to open or close the valve; 00- operating camsurfaces on the sleeve and stem whereby rotation of the stem in eitherdirection will tend to close the valve; a cam surface on the capco-operating with a cam surface on the stem to prevent closing of thevalve by rotation of the stem in one direction; and means by whichrotational adjustment of the cap will reverse the valve action.
